UNITED STATES PATENT OFFICE- ROBERT H. GEHRKE, OF LIIBIB Y, MONTANA.

rnnss To all whom it may concern:

Be it known that I, ROBERT H. GEHRKE, a citizen of the United States, residing at Libby, in the county of Lincoln and State of Montana, have invented new and useful Improvements in Presses, of which the following is a specification.

This invention relates to a fruit or vegetable press and the principal object of the invention is to provide means whereby the fruit or vegetables may be forced through the press with the minimum amount of exertion on the part of the operator.

Another object of the invention is to pro vide means for clamping the press to a table or other support and to so construct the frame that the press will be held above the table so that a receptacle may be placed beneath the same upon the table to receive the material falling from the press.

A still further object of the invention is to provide means whereby the piston of the press may be quickly and easily removed from the cylinder when it is desired to place the material in the cylinder.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side view of the invention;

Fig. 2 is a sectional view on the line 2-2 of Fig. 1;

Fig. 3 is a detailed View of the supporting ring for the cylinder;

Fig. 4 is an enlarged sectional view.

In these views 1 indicates a standard which is of the shape shown so that when its base is resting upon the edge of a table its upper portion will be located above and inwardly of the table. This standard is provided with a base 2 which is adapted to rest upon thetable and a clamp 3, carrying a thumb screw 4 is pivotally mounted to the standard by the pin 5. By this means the standard may be clamped to the edge of the table 6. 7 indicates aperforated cylinder for containing the material to be pressed and this cylinder is supported by the ring Specification of Letters'latent.

member 8 which is provided with a channeled part 9 which engages the inwardlyextending' portion of the standard and is secured thereto by the rivet 10. In this way the cylinder is located above the table so that a receptacle or dish may be placed on thetable below the cylinder to receive the material being pressed therefrom. A piston 11, which is adapted to. engage the material in the cylinder, is carried by a worm shaft 12 which passes through an opening in the head 13 formed at the upper end of the standard. The upper end of this shaft is provided with a crank 14 by which the same may be rotated. A spring controlled plunger 15 is carried by said head 13 and the end of this plunger is adapted to engage with the groove in the shaft 12 so that as said shaft is rotated it will be caused to move either downwardly or upwardly according to the direction in which it is turned. When it is desired to move the shaft quickly without rotating it, the plunger may be moved outwardly against the tension of its spring 16 so that its inner end will leave the groove in the shaft and thus permit the shaft to be moved longitudinally without being rotatedJ This will permit the piston to be quickly withdrawn from the cylinder to permit the plac ing therein of the material to be treated. I form the outer end of the plunger with a knurled member 17 and a sleeve 18 surrounds the outer part of the plunger and incloses the spring 16. This said spring has one end bearing against the shoulder formed on said sleeve while its other end bears against the shoulder formed on the plunger.

The sleeve has screw-threaded engagement with a screw-threaded recess formed in the head.

It will thus be seen that the vegetables or fruit placed in the cylinder will be pressed through the perforations therein when the I piston is brought in contact therewith by rotating the handle 14 and this operation may What I claim is A device of the class described comprising a standard having inwardly extended portions, a clamp pivotally connected to the lower end of the standard, a perforated cylinder, a ring member removably supporting said cylinder and having a channeled .ex-.
